To all whom t mo/y concern:

Be it known that I, HAROLD L. WHITE, a citizen of the United States, residin at Dinuba, in the county of Tulare, and tate of California, have invented certain new and useful Improvements in an Air-Cleaning Device, of which the following is a specitication.

The present invention relates to an air cleaning device used in connection with internal combustion engines and especially 'those used on the Fordson tractor and has for its principal object to provide simple and efficient means for cleansing the air from all particles of dirt and dust which are usually contained in the air about tractors working in agricultural elds.

' Another important object of the invention is to provide a device of this nature which is capable of being manufactured at comparatively low cost, which is capable of being used in conjunction with a portion of the cleaning device such as is now used' on Fordson tractors and which will be extremely reliable in operation.

In the drawings ligure 1 is a side elevation of the device, an

Figure 2 is a vertical'section taken therethrough showing the same attached to the casing of the air cleaner nonT used upon Fordson tractors.

Referring to the drawing in detail it will and the two spaced filtering compartments 8 which are adapted tobe situated on either side of the flue 4 and depend into the casing 1 so as to terminate a distance from its bottom. These filtering compartments 8 are constructed with a depending wall 10 which is spaced from the end wall of the casing 5 and terminate a distance from the bottom of the compartment and are there provided with a ba ed plate 11 which terminates a distance from the inner wall of the compartment 8.l Another baffle plate 12 extends from the inner wall ofthe compartment 8 above the baille plate 10 and a third baie plate12 extends from lthe'depending wall 10 above the above .baliie plate 12. A mass of oil soaked porous material such as moss 14 is situated between the baiile plates 11, 12 and 13 and between the plate 6. This plate 6 is provided with a plurality of apertures 15 in registry with the compartment 8 disposed between the inner wall and the depending Wall 10 so asvto allow the air to escape intol the cover compartment 2 and out through the outlet 3. The outer wall of the compartment is providedwith an aperture 16'at its upper end so that the airk may pass into the compartment 8.

As is disclosed by the arrows in Figure 2 the path of the air is as follows. The air enters into the bottom end of the Hue 4 into the pocket 7 then passes downwardly between the inner walls of the compartment 8 Aand the flue 4 into the lower portions of the casing which contain oil as is disclosed at 18. This oil collects the heavier particles of dust and dirt from the air and the air then passes upwardly in the casing and throughV the apertures 16 into thev compartments 8 passing downwardly under the Abaffle plate 11 through the oil soaked porous lmaterial 18 and about the bailie plates 12 and 13, then through the apertures 15 into the cover compartment 2 and finally through the outlet 3.

Having thus described my invention what I claim as new is v A device of the class described including a top late, a pair of spaced compartments depen ing from the top plate so as to form a pocket therebetween, a depending wall extending from the top plate in each compartment so as to be spaced from its walls and a plurality of baille plates situated between one wall of the compartment and the depending wall, and a mass of oil soaked porous material supported on said baille plates. l' 'y In testimony whereof I afx my signature in presence of two witnesses.
